Hopefully not major but issues none the less. In desperate need of help..... install a sub and amp duo package with lp7 converter. Once 99% complete started truck everything worked. Turned truck off and connected power cable to battery. Truck now won't start all aftermarket lighting still works, key fob and alarm still work and one headlight strangely enough still works. truck is 100% unresponsive as far as rolling over or signs of life at all besides previously stated........ anything is a help at this point?????????

You shorted something somewhere. Track your steps back and look at fuses on the battery. Also it would help if you had a volt meter to diagnose. Best of luck

If something got inadvertently wired to a communication line, this will happen. Time to retrace ALL your steps, and remove them one at a time until it cranks.

Ran the battery down?

Yeah, great point! So easy to forget the basics - I do it all the time on these internet WAG (Wild Assed Guess) sessions.
